If A=[[3,2],[1,4]], then A(adj A)=

If A=[[1,2],[4,2]] , then show that |2A|=4|A|

If A = [[1,2],[4,2]] , then show that |2A| = 4|A|

Answer the following questions.If A=[[1,2],[3,2],[-1,0]] and B=[[,1,3,2],[4,-1,-3]] ,show that AB is singular matrix.

If A = [[1,2],[4,2]] then show that |2A|= 4|A|

if A = [[3,2],[1,4]] , then A(adj A)=

If Matrix A= [[2,-1],[3,2]] , then show that A^2-4A+7I=0 and hence find A^-1 from this equation.

If A = [[2,4],[3,2]] and B = [[1,4],[-3,2]] ,then 2A + 3B =

If A=|[1,2],[3,2]| ,then show that |2A|=4|A|

If A=[{:(1,2),(4,2):}] , then show that |2A| =4|A|
